Common Mistakes to Avoid
❌ Not using dimensional weight
Carriers charge by dimensional weight (L x W x H / 139) if larger than actual weight. Light, bulky packages cost much more than expected.
❌ Ignoring fuel surcharges
USPS, UPS, and FedEx add fuel and residential surcharges that can add $3-7+ to each shipment.
